JOSEPH SARGENT KEMP, OF MAGOG, QUEBEC, CANADA.

WHEELED STUMP OR STONE LIFTER.

SPECIFICATION forming part of Letters Patent No. 397,807, dated February 12, 1889.

Application filed June 6, 1888. Serial No. 276,179. (No model.) Patented in Canada November 10, 1886, No. 25,313.

To a'ZZ whom, it Hwy concern:

Be it known that I, JOSEPH SARGENT KEMP, of township of Magog, Province of Quebec, Canada, a citizen of Canada, have invented certain new and useful Improvements in \Vheeled Stump or Stone Lifters and Con= veyers, (for which I have obtained Canadian Letters Patent, dated November 10, 1886, No. 25,813,) of which the :t'ollowing is a specification, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is aplan view of the same. Fig. 3 is a partial rear elevation of the machine, shown with wheels off and without any hoistinggear.

The first part of my invention relates to the combination of four upright posts or standards and the principal cross-bar of the stonelifter, two of the said standards to be placed on one side of the machine, one on each side of the wheel, and two of the said standards on the other side, one on each side of the other wheel, in such a manner as to render them capable of resisting the severe strains to which they would be subject. The second part of my invention relates to the combination,with the said cross bar or bars, of a shiftinghoist-gear in such a manner that the center of gravity of the load may be placed at any desired point.

- In the drawings, K K K K are the four upright posts or standards, between which the wheels Y of the machine revolve upon the pins or axles y 1 which pass through the said standards and are held in position by bolts E E, one end of which is fastened to the stringers m m, as shown by "v v. The said standards are connected with the cross-bar (or crossbars) p by being notched. and securely bolted and braced, as indicated.

The shifting hoist-gear is composed of the ratchet e, the lever-socket u, the blocks (1 (Z, securely bolted to the short uprights 71 71, the loose pins 9 g, the chain -sheave u, and the clicks or paw is Z) and 0, combined as indicated, the whole of said parts sliding upon and between the longitudinal bars (or bar) ii, which rest upon the cross-bar p and the post J, securely bolted, as indicated. The post J is braced and secured to the front cross-bar, 0,

which is rigidly secured to the bars or stringers m on and Z Z, and these in turn are bolted to the middle cross-bar, n. The pole or reach sis bolted to the said cross-bars, the post J, and to the longitudinal bars 2' 2 by means of the straining-rod Q,-the upper end of which is secured in the cross-piece 0", which lies across the bars 'L' "i, and, together with the remaining timbers of the machine, forms a very rigid truss for the support of the load. The loose pins 9 g are used to lock the hoisting-gear at any desired point by being passed through holes in the blocks (Z (Z and into holes A A, placed at any required distance apart in the longitudinal bar or bars 2 '1'. The loose bolt to, placed in any hole, B, in the longitudinal bars, serves as a fulcrum for a lever, which, placed against the short upright 72, gives a means of shifting the load before the pins g g are inserted to lock the load in position.

F is a chain of ordinary construction, adapt-ed to fit and properly engage with the chain-sheave \V, and provided at its lower end with the grappling-hooks rose, of ordinary form. This combination of four standards or upright posts, as described, forms a more rigid support for the load and gives more uniform bearing upon the wheels and axles of the machine than can be obtained by any other method, and the shifting hoisting-gear possesses many advantages over other machines of the kind, inasmuch as thatis an easy means of regulating the position of the center of gravity of the load relative to the wheels, as aforesaid. This is particularly useful in going up or down hill, for the load may by this means he brought as nearly over the axle as desired, thus avoiding any tendency to tip the front end of the machine up. The cheapness and simplicity of the construction of this machine are other advantages.

This machine may have a tongue for horses or oxen, or it maybe attached by short reach to forward pairs of wheels.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. An apparatus comprising upright posts, in the lower ends of which the axles y are mounted, a lower frame composed of the bars Zm n o, to which the pole is connected, an upper frame mounted upon the posts K and .l', and consisting elf the bars 1) and L 1", and frame connected to the axles and pole, $111)- the hoisting mechanism mounted on the bars stmltially as described.

1', substantially as described. In witness whereof I have hereunto set my 2. A wheeled stump and stone lifting :tp- 1 hand this 29th day of May, 1888.
